SEAMlNG-MACH INE,

SPECIFICATION forming part of Letters Patent No. 314,336, dated IVIarch 2%, 1885.

' Application filed November 26, 1884. (No model.)

To all whom it may concern:

Be it known that I, EDMUND JORDAN, of Brooklyn, in the county of Kings, State of New York, have invented an Improvement in Scanning-Machines for Closing the Seams on the Ends of Sheet-Metal Cans; andldo hereby declare the following to be a full, clear, and ex" act description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of the specification.

My invention consists of aseaming-machine for closing the head-seams upon sheet-metal cans.

It consists in mechanism whereby the seaming-rolls are causcd'to travel in contact with the head-seam throughout of whatever exterior the seam may be, the canbody remaining stationary, and consists in the mechanism hereinafter more fully described and claimed. 1

In the accompanying drawings, Figure l represents a front view of the machine.- Fig.

2 isa vertical section of the same, taken at line 00 m, Fig. 1. Fig. 3 is a horizontal section taken at line y y, Fig. 1. Fig. 4. is a perspective view of a link carrying the guide or canroll. Fig. 5 is a perspective View of a sec ondary link carrying the seamingrolls. Fig. 6 is a sectional view of the seam before it, has been operated on, and Fig. 7 is the same view after the seam has been operated on. represents a view of the seaming-rolls and cams and the mechanism for operating the seamingrolls, and a section of one of the clamping-disks. Fig. 9 is a top view of Fig.

. 8. Fig. 10 is an end View of Fig. 11. Fig. 11

represents a portion of Fig. 8, showing the seaming-rolls moved outward to clear the plate. This'is accomplished by the upward movement of the conical sleeve. Fig. 12 is a section view of a seaming-roll and thespindle upon which it revolves. Fig. 18 is a section of the pocket in the end of the cam-roll-supporting links, containing a compression-spring for keeping the seaming-roll to its work.

Having'described my invention by reference to the figures illustrated in the accompanying drawings, I will now proceed to describe it by reference to the letters marked thereon, in which similar letters of reference refer to corresponding parts throughout.

A represents the frame mounted on legs B.

0 represents a sheet-metal can in position to be operated on.

E represents the stationary centering and clamping disk fitted to the required shape.

D represents thelower centering and clamping disk fitted to the required shape. This disk is rigidly attached to the upper end of the movable stud D both having an intermittent vertical motion for centering, clamping, holding, and releasing the can when the seam has been closed. To accomplish this an adjusting-nut, D is provided on the lower portion ofthe movable stud, against which a sleeve carrying an anti-friction roll rests.

D is the sleeve, and D the roll. The roll works on a cam.

D represents the cam which is attached to rock-shaft D which is operated by treadle D (Z represents an intermittentlyrevolving sleeve adapted to rotate on stud D On this sleeve are two arms, (1 and d Fig. 3. Each arm carries a link pivoted in it. Figs. 3 and 4, represent these links.

(Z and (1 represent cam or guide rolls which are pivoted in the ends of links d and (1. These cam or guide rolls travel in a cam-groove '80 hereinafter described.

d and cl are secondary links pivoted to links d and d. In the opposite ends of each of these secondary links is pivoted a seamingroll, (1 and d Figs. 3 and 5, so shaped as to press the seam to be operated on between it and the clamping-disk.

(1 is a pocket in links 01' and d, in which an adjusting compression spring of sufiicient strength to keep the seaming rolls to their 0 work is placed. This spring bears against the secondary link which carries the seamingrolls, thereby keeping themto their work.

On sleeve dare two pairs of projecting lugs,

d (1". (Shown in dotted lines in Fig. 3.) Be- 5 tween each pair of theselugs is pivoted a link, (1. (Shown in Fig. 1.) In the middle of these links is a raised surface, which bears against a projection in the side of the secondary links (1 and d The lower end of these links carries an minimum roll, which works on the face of a conical sleeve.

d" and d,

(1 represents the conical sleeve fitting over and sliding on the main sleeve d. This conical sleeve is movable vertically by means of a pin sliding in and through a hole in the hub of the gear-wheel, the lower end sliding on the cam which actuates the pin and sleeve.

d represents the pin, d the gearwheel, and d" the stationary cam which actuates the pin and sleeve vertically to expand the depending links d, carrying the anti-frictionrolls, thereby crowding the projecting surface on the links against the secondary links, carrying the seaming-rolls d and d thereby forcing them from the seam and disks to enable the operator to insert or remove a can.

(i represents a grooved cam of the desired shape to permit the can to be operated upon by the seaming-rolls. Cam or guide rolls d and (1 work in this cam-groove, thereby keeping the seaming-rolls to their work. d represents a yoke for supporting and guiding the mechanism before described. This yoke has a vertical reciprocating inotion,and works in suitable guides or ways in the frame. (Shown in Figs. 1 and 3 in dotted lines.)

01 d represent caps for keeping the yoke in the guides or ways. The yoke is fitted over and rigidly attached to stud D and is actuated by means of cam D on rock-shaft D operated by treadle D.

d d represent two connterbalance-levers pivoted to the frame at d d. The inner ends of these levers bear against a projecting flange on sleeve D.

d d represent counterweights. By means of the lever and weights the moving mechanism is nearly balanced, thereby lessening the labor of the operator and preventing concussion when the mechanism is moved downward.

(Z is a gear-wheel fitted over and rigidly held on sleeve d. This gear-wheel meshes into a broad-face pinion-wheel, d), rigidly held on vertical shaft S. Through this mechanism a vertical motion isimparted to the sleeve-links,

guide or cam rolls, and the seaming-rolls.

E represents a stationary centering and clamping disk of the required shape to fit the end of the can to be operated on. This disk is fitted and rigidly attached to stud E, Fig. 2. The upper end of this stud islet into and held in hub E in the frame.

6 represents an intermittently revolving sleeve fitted over and revolving on stud E.

e and 6" represent two arms on the lower end of sleeve 6.

e and a, Fig. 1, represent links pivoted in the extremity of the arms. These links are similar to those shown in Fig. 4:. The opposite ends of these links carry a guide or cam roll. 6 and 0" represent these guides or cam rolls.

6 and 6 represent secondary links, similar to that shown in Fig. 5. One end of these links is pivoted to links 6 and e. The opposite end of the secondary links carry a seaming-roll of suitable size and shape for closing the seam. e and 0 Fig. 1, represent these seaming-rolls.

In links 6 and e is a pocket similar to d, Fig. 4, which carries a compression-spring, which bears against the secondary links, carrying the seaming-rolls, to keep them to their work, as before described. 6, Fig. 1, repre sents one of the spring-pockets.

On sleeveeare two pairs of projectinglugs, one pair of which is shown and marked 6, Fig; 1. Between each pair of lugs is pivoted a link, one of which is shown in Fig. 1. e is the link. In the middle of the link is a raised surface, which bears against a projection on the side of the secondary links e and e. The upper ends of the links carry anti-friction rolls, which work on the face of a conical sleeve.

e is the conical sleeve, sliding upon and revolving with the main sleeve e. This conical sleeve is kept in place by a compressionspring, s in Fig. 1. A downward motion is imparted to this sleeve by a pin sliding in and through a slot in the hub of the gear-wheel, the upper end of the pin projecting through the hub and sliding on a stationary cam. 6 is the pin. 6 is the gear-wheel, and e" is the stationary cam on which the pin slides. the conical sleeve-pin and stationary cam is to expand the links a, which thereby actuate the links carrying the seaming-rolls, swinging them clear of the disk to enable the operator to insert or remove a can.

6 is a stationaryoam of the desired shape to suit the contour of the can to be operated upon by the seaming-rolls. Cam orguide rolls 6 and a work in this grooved cam, keeping the seaming-rolls to their work.

Gear-wheel e is fastened to sleeve 6. the two rei'olving together on the stud E. This The office of gear-wheel meshes into pinion-wheel e se-- cured to upright shaft S, whereby the sleevelinks, cam or guide rolls, and seaming-rolls derive their rotary motion. On theupper end of shaft S is a beveled gear-wheel, which meshes into a similar gear-wheel on the hori zontal drivingshaft. S and S represent the beveled gear-wheels, and S the main drivingshaft. 7 V

P represents a clutch-pulley of well-known construction, which operates intermittently by means of a conical slide, S tongue S actuated by shifter S attached to a shifter-rod, S by means of a bell-crank, S, pivoted to the frame at S". By means of connecting-rod S the lower end connects with a lever, S, pivoted loosely on rock-shaft D. Rigidly attached to the same rook-shaft D and side by side with lever S is a short crank, S having a projecting pin, S, from the side thereof. This pin engages with the upper edge of lever S during a part of the stroke.

By means of this mechanism the operator, by pressing on the treadle, centers and clamps the can between the disks, and by continuing the pressure brings the projecting pin S in contact with lever S thereby engaging the I sheet-metal cans, the combination of theseamclutch-pulley and putting the machine in operation. After the seam has been closed on the can by the seaming-rolls traveling in contact with it the stationary arms 1" and e" are so timed asto swing the seaming-rolls clear of the can and disks. Immediately following this a projecting cam on thelower side of gearwheel e comes in contact with lever S, pivoted to the frame at S", the opposite end playing between two collars, S S, rigidly held on connecting-rod S, thereby imparting a vertical motion to the connecting-rod, by means of which the clutch is relieved and the rockshaft D, with its cam D and treadle D is reversed, lowering the yoke d, and the mechanism therewith connected, thereby releasing the can, the machine remaining at rest.

In the drawings a square cam and disks are shown. Other shapes may be used. Two seaming-rolls are shown at each end of the can. One or more may be used.

WVhat I claim as new, and desire to secure by Letters Patent, is

1. A machine for closing the seams which secure the heads to the bodies of non-circular sheet-metal cans having, first, a pair of centering and clamping disks conforming to the shapes of the heads of the cans, and constructed and arranged to center, clamp, and retain the can stationary; second, one or more seaming-rolls, with mechanism whereby the same are retained against and revolved around the can throughout the entire length of the seam of whatever contour the seam may be.
